As you say, it is patchy, not only geographically but between the services, I have been very impressed by NHS services delivered through Consultant and CPN and more recently when John was admitted to hospital with a chest infection.
Social services seem to be less efficient or understaffed and resourced. It is hard to work out at times exactly what their problem is. If I call into their local office there seems to be a surplus of people wandering about or sitting at desks but the front line staff who need to be making major decisions and calling out to do assessment seem to be thinner on the ground.
